/**
 * sends a trigger when the performance goes below a threshold
 *
 * @remarks
 *
 * The performance is a number that goes from 0 to 1.
 *
 * It is calculated like this: `performance = current FPS / desired FPS`.
 *
 * Therefore, a performance of 1 means that the scene is running smoothly.
 *
 * A performance of 0.5 means it is quite choppy. (around 30fps, if the desired fps is 60)
